Dell PowerEdge M640 VRTX Memory

This 16GB DDR4 2933MHz ECC RDIMM is built for the Dell PowerEdge M640 VRTX server platform. It targets administrators who need registered error-correcting memory to maintain data integrity in a compatible blade or converged system.

Single-Module Upgrade Path

The package contains one 16GB stick, so capacity grows in 16GB increments per available slot. Registered signalling and ECC let the platform correct single-bit errors without adding unbuffered modules that the system cannot accept.

DDR4 2933MHz CL21 Registered

The module runs at DDR4 2933 (PC4-23400) with CAS latency 21 at 1.2V in a 288-pin RDIMM form factor. This exact speed, voltage and registered type must match the server memory controller or the system will not post.

Questions about this item

Will the 288-pin DDR4 RDIMM need any firmware updates or battery replacements over its service life?

No firmware or battery maintenance is required for this registered ECC module; it operates passively once installed in a compatible Dell PowerEdge M640 or VRTX system.

What thermal limit appears first when the 16 GB 2Rx8 module runs continuously at 2933 MT/s?

The module has no heat spreader, so the DRAM junction temperature reaches its rated maximum before any other component becomes a bottleneck under sustained load.

How much power does the 1.2 V registered DIMM draw and how much noise does it add when the server runs all day?

At 1.2 V the DIMM consumes only a few watts and adds no audible noise because it has no moving parts or active cooling.
